No it doesn't. First, the changes may not be neutral. I will presume that you are intelligent enough to grasp that idea the mutations in and of themselves are neither advantagous nor disadvantageous, and the they have no purpose. Evolution happens when the mutations (and other mechanisms that increase genetic diversity) are acted upon by other mechanisms of evolution. Even in natural selection there is no purpose. Natural selection is differential reproductive success. Some organisms tend to produce more offspring because they have characteristics that give them an advantage in a particular environment.
